That probably means that media-ctl got compiled against a different media controller API version than the one running on your system. Make sure you set the --with-kernel-headers= to the path to kernel headers for the kernel running on your system. > Why 'Unable to start streaming: 32' - is this an EPIPE error? That means the pipeline hasn't been configured properly.
